Bizarre Problem with USB 2.0 Hub and Bluetooth

trequ · 11-26-2004, 07:49 AM

Hello,

i have a bizarre problem here and need some help.

I am realy new in the linux os. I use Suse 9.2 since 2 weeks.

I have to get an USB Bluetooth Dongle on a USB 2.0 Hub to work with
Linux (Suse 9.2)

Problem description:
- The Bluetooth Dongle works, if connected to pc without USB Hub.
- The Bluetooth Dongle also works, if conncected to an USB 1.1 Hub.
- But if i connect the Dongle via USB 2.0 Hub i get this error in var/log/messages:

Code:

Nov 26 09:18:46 linux kernel: usb 5-4: new high speed USB device

Nov 26 09:18:55 linux kernel: hci_cmd_task: hci0 command tx timeout

Enviroment description:
- Suse Linux 9.2, Kernel 2.6.8-24-default
- Asus P4P800S SE or Asus P4C800 Deluxe
- USB 2.0 Hubs with trouble are: Cypress 4-port CY7C65100 and NEC 7-port µPD720113
- USB 1.1 Hub (working): Alcor Generic USB Hub, 4-port
- Bluetooth Dongle with CSR chip

I don´t understand, why the Bluetooth Dongle is not working.
If i connect an USB Stick to this hubs, the mass storrage stick works.

Any help is greatly appreciated.

I too had this same problem.What i did was: USE="usb bluetooth" emerge openobex. Also check if the rfcomm support is compiled in your kernel and that the rfcomm module is loaded.
(I'm a newbie, don't mind if I am wrong somewhere)

Hello there,

I have exactly this same problem, have you resolve it???

So I'm using a USB Bluetooth Dongle (D-Link DBT 122) to work on a linux system. I want to exchange datas with a Nokia Cell Phone which also uses Bluetooth.

On this purpose, I'm using the OBEX Push Daemon tools which facilitate the binary objects exchange between two devices. Among those tools, I want to use the opd command which permit to run a Daemon to continually listen and receive objects via Bluetooth. To run it uses something like:

Code:

opd --mode OBEX --channel 10 --path /root/bluetooth_inbox --sdp --metadata

which will use Bluetooth, listen on channel 10, register the service sdp, store receive files in /root/bluetooth-inbox and save extra data about the files you receive (i.e. the address of the Bluetooth device the files came from).

So it seems a little bit complicated for me(because I'm a newbie) but the problem I have is that when i launch the OPD command, I have those traces:

Code:

#opd --mode OBEX --channel 10 --path /root/bluetooh-inbox/ --sdp --metadata

opd[246]: OBEX Push Daemon - version 0.2 started

opd[246]: OBEX Object Push service registered with sdpd


opd[246]: Failed to register BtOBEX server on RFCOMM channel 10. (-121 / 0)

Thus the OPD command doesn’t work and the OBEX server cannot listen on channel 10 even if the rfcomm protocol is active on my kernel and the same problem is present with all other channel.

Have you an idea on the subject, or some information which lead to resolve the Problem?
I do some researches on this problem but the web sites and forums which mention this problem are rare.

Thanks in advance,
Kiba

Hi,

You did look at the OP date?

You should create a new post to get better exposure. Include all the data or information.

By chance are you using a unpowered USB hub?

Thanks for reply, you're right. I will create a new post.

And no, I'm not using a unpowered USB hub. I connect directly the USB Bluetooth Dongle to the USB port of my linux system.
